摘要： In order to ensure constant valve-switching time, irrespective of variations in viscosity, and in order to dampen, to the lowest possible constant level, the noise produced when the valve is operated, the invention proposes that a seal (3) is fitted between the outside surface of the armature (5) and the inside surface of the valve housing (1) and, parallel to the seal, a diaphragm (16) in the armature (5), a permanent hydraulic-fluid connection being established between the hydraulic-fluid chamber (4) in the armature (5) and the hydraulic-fluid space (12) located outside the armature (5).

摘要： In a circuit arrangement for a brake system with antilock or anti drive slip system and with switching circuits for detecting bends, side reference speeds (13, 14) are derived by means of selection circuits (8, 9) each of which selects a controlling wheel speed in accordance with given criteria and by means of filter stages (10, 11) with variable time constants (12). A difference signal (DVS) (15) whose amplitude can be varied by counter coupling is derived from the side reference speeds (SRGL, SRGR). An adaptation circuit (18) triggered by this difference signal (DVS) in function of the vehicle reference speed (VREF) influences the control thresholds of the antilock and anti drive slip system (7) in order to adapt the control to the specific characteristics of a bend being negotiated.

摘要： In an antilock hydraulic braking system, a throttle is inserted in the throttle valve (8) in the brake line during brake slip control. The pumps (12, 13) pump the hydraulic fluid through the throttle to the wheel brake. The pressure in the wheel brake is controlled only by an outlet valve (11) the open cross-section of which is chosen so that the quantity of hydraulic fluid discharged through the outlet valve (11) is greater than the quantity of hydraulic fluid delivered by the pumps (12, 13) to the wheel brake via the throttle. Hence, when the outlet valve is open, the pressure in the brake decreases, whereas when the valve (11) is closed, the pressure in the brake increases. The invention relates to different ways of controlling the throttle valve (8).

摘要： The invention relates to a pump which, with the simplest and most compact structure, ensures the leak testing of the pressure valve (5) both outside and inside the pump housing (8), which ensures the simple interchangeability of individual components, e.g. the pressure valve (5) or the valve seat body (2) when necessary, if a leak is detected during the testing process. To this end the outside surface of the valve seat body (2) facing the cover (1) has a conical chamfer (3) on which an annular projection (4) of the cover can be fitted to form a seal and radially expanded into an interference fit.

摘要： A hydraulic, antilock braking system has a pump (8) and a master cylinder (1). The valve for regulating the pump pressure is integrated in the master cylinder (1) and is composed of a combined seal (30, 34) that cooperates with a compensating bore (36). The seal (30, 34) is composed of an inner elastic ring (37) and an outer sliding ring (38). The communication required between the reservoir (7) and the brake circuits in order to fill up the brake circuits through a nonreturn valve is established through the nonreturn valves (10, 11) of the pump (9). A packing (41) may be added to the double seal (30, 34) in order to reliably seal the working chamber (39, 40) even when small leakage currents occur through the double seal (30, 34).

摘要： A circuit arrangement for a brake system with anti-lock control generates pulse-shaped brake pressure control signals. In order to increase the pressure again after a pressure drop, the brake pressure is first controlled with a steep gradient and then with a flatter gradient. This is achieved by means of a variable pulse (P1) and by means of short constant pulses (P2) in rapid succession. Switch circuits determine the pulse and pulse pause times (T1, T2, Tk) which determine the pressure increase - from the duration of the presure build-up (T1) during the build-up with steep increase in the preceding cycle - from the duration (T1 + nT2) of the total pressure build-up in the preceding cycle - from the duration (T0) of the preceding pressure build-up. The pulse times are chosen so that at constant coefficient of friction and uniform preliminary pressure the locking limit of the wheel is attained again after a predetermined time interval or after a predetermined number of pulses. The duration of the variable and constant pressure build-up pulses is computed from the pressure build-up of the preceding pressure or read from a stored table.
